Abstract

Most of land in Pakistan comes under rainfed condition especially in Baluchistan and some areas of Sindh where rainfall is less than requirement of crops to grow average. Development of cultivars with high yield is the main goal in water limited environments but success has been modest due to the varying nature of drought and the complexity of genetic control of plant responses. Fifteen drought tolerant genotypes of wheat which were received from ICARDA were evaluated along with drought tolerant local check variety Khirman under water stress condition. The experiment was conducted at field area of Nuclear Institute of Agriculture (NIA), Tandojam. Experimental design was Complete Randomized Block Design (RCBD) with three replications. Different six yield and yield associated traits were recorded such as, number of spikelet’s spike-1, number of grains spike-1, number of Grains spikelets-1, biological yield plot-1, grain yield plot-1(g) and harvest index. Check variety Khirman produced significantly high values for three different traits viz., number of spikelet’s spike-1, number of grains spike-1, number of Grains spikelets-1, while DSBWYT-5 was good in biological yield plot-1, grain yield plot-1(g), however highest harvest index was produced by DSBWYT-10. These results indicate that these genotypes can perform well under drought condition, hence may be utilized in upcoming breeding programs.
